Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To enable a superconducting magnet to generate a highly accurate magnetic field by reducing the vibrations transmitted to the magnet by mounting a GM refrigerator on a vacuum vessel with an elastic material in between. SOLUTION: A GM refrigerator 1 is mounted on a vacuum vessel 2 with vibration isolating adapters 8 in between. Each adapter 8 is composed of upper and lower metallic flanges 8a and 8b and a rubber body 8c which is molded to the flanges 8a and 8b. Each adapter 8 can also be constituted of bellows. Though the adapters 8 are composed of an elastic material, the adapters 8 must support not only the weight of the refrigerator 1 itself, but also the load applied to the refrigerator 1 from the atmospheric pressure, because the inside of the container 2 is maintained in a vacuum. In addition, a helium-free superconducting magnet device uses heat conductive material 9 and 10 containing copper net wires having excellent thermal conductivity for cooling objects to be cooled.  When the magnet device is constituted in such a way, the device can generate a highly accurate magnetic field, because the propagating route of vibrations becomes largest at the parts of the adapters 8 which support a motor section 6.

Title: Semiconductor memory device
Inventor: FURUHATA MAKOTO
IPC: H01L27/10
Filed: 1984-11-22
Abstract: PURPOSE:To ensure the simple reading of memory information, by providing a bipolar transistor, which is formed in the island of an electrically independent semiconductor with respect to a memory cell, between the memory cell and bit lines. CONSTITUTION:When a word line W is selected, an injection current, which is supplied to a memory cell M, is increased. When bit lines B1 and B2 are selected, only the memory cell M, in which the injection current Ic is increased, takes a current from the selected bit line B1 or B2 by a large amount. Thus the memory cell M at intersections of the word line W and the bit lines B1 and B2 is selected. The change in current corresponding to the memory information ('1' and '0') of the selected memory cell M complementarily appears on the selected bit lines B1 and B2. The current change is detected by a sense amplifier. Thus, the memory information in the selected memory cell can be read out. In this way, the reading of the memory information in the selected memory cell can be performed simply and positively.

Abstract: PROBLEM TO BE SOLVED: To discharge low temperature molten salt generated in a heat exchanger in a continuously easily post-treating shape by providing a comminuting mechanism for comminuting the salt adhered to the exchanger, and providing a removing mechanism for removing comminuted material from a channel. SOLUTION: Whis waste disposing facility comprises a comminuting mechanism 7, a removing mechanism S, and a secondarily burnt air supplying mechanism 10. The mechanism 7 receives lump-like low temperature molten salt to be separated from an inner wall surface of an air preheater 4A, and comminutes it. That is, the separated and dropped salt 6 is agitated, comminuted, and reduced in diameter by flowing sand 11. The sand 11 is fluidized and agitated by secondarily burnt air 12 supplied from the mechanism 10. Since a corner of the salt 6 is polished by polishing action of the sand 11, it is reduced in diameter and made in shape and size uniform. The salt 6 reduced in diameter by a fluidized bed 7A is conveyed to a separator 8 together with the sand 11. In this case, the salt 6 is separately recovered from the sand 11, and again returned to the bed 7A by a pneumatic conveyor P.
